We are very excited to announce the launch of the FriendFeed API, which enables developers to interact with the FriendFeed site programmatically. It's designed to make it possible for anyone to improve FriendFeed or integrate FriendFeed into other applications. You can develop a FriendFeed interface for a mobile phone, build a FriendFeed widget for your blog, or develop an application that makes it easy to post photos to your feed from your iPhone.

If you are a non-techie, you can learn more about what the API does and how you will interact with third party FriendFeed applications by reading the FriendFeed API user FAQ.

Since the API is new, it is a work in progress, and we expect to make a number of changes in the next few months. Developers can send us feedback in the FriendFeed developer forum.

We would like to thank the folks who took the time to send us feedback on earlier versions of the API, particularly Benjamin Golub, DeWitt Clinton, Eran Hammer-Lahav, and Dave Winer. We haven't yet implemented all of their suggestions (OAuth is coming!), but we wanted to get it out to all of you for feedback in the meantime.

We are eager to see all the innovative applications people will create with the API. Happy coding!

Brilliant service, however my feed from jaiku doesnt seem to update at the moment. And the @username while it works brilliantly on twitter sends you to @username.jaiku.com/username regarding @:s on jaiku =o, I love seeing FF grow every day =o) Cheerios!

I really like your service. But from my point of view, there's a problem: feeds with greatly differing posting frequencies. In part, you already solved this. You make bundles of series of entries. But what about different frequencies of services in general? Take, for example, my FriendFeed account ("lambo"). My last blog entry (on http://log.netbib.de/archives/author/lh/) is from several weeks ago. But this feed is much more important to me and my readers than my del.icio.us-bookmarks or my Google Reader shared items. Right now, on FriendFeed nobody gets to see this last blog entry, because it's buried under many bookmarks.What about generating an overview of the latest 2-3 items from the less frequently updated feeds?

Hi Guys, great job on the API - we have already implemented it (on the dev server) so that fav.or.it can share back to FriendFeed - http://blog.fav.or.it/2008/03/26/friendfeed-support-added-to-favorit/ Only question I have is there a way to show up the service that is sending you this data? would be great to have a little fav.or.it icon show up next to any links we send you.

Cool...Javascript API and Json will change lots of thing. Sevice Iocn is really needed because it makes service identification quick in feedreaders. And finally....add more services like Facebook and MySpace.

This is great, I wrote a scraper for hypem.com in 15 mins. But it would be better to be able to modify the action description from the default "posted a link" to some arbitrary string (e.g. "X liked a song on hypem.com")

It doesn't matter what you add. If I have to enter my friends manually when they're available automatically on socialthing, I know which one I'm going to use. I'm not going to randomly guess people's usernames for friendfeed or enter every single username manually. This should be automatic, the data and external API's exist.

Today, BigOven.com became the first foodie social network to support FriendFeed. Now you can alert your friends when you rate a recipe highly, post a photo, a cooking video, or more!

FriendFeed team -- great work on this cool service. We'll do what we can to promote the use on our site, which is about 1 million uniques a month and growing nicely (but not quite as fast as FriendFeed!)
